STEAM-GENERATOR AND FURNACE.

SPECIFICATION forming part of Letters Patent No. 234,123, dated November 9. 1880.

Application filed March 25, 1880. (No model.) Patented in Germany March 30, 1879, in Belgium August 13, 1879, in France September 3, 1879, in England October 3, 1879, and in Italy October 16, 1879.

To all whom it may concern:

Be it known that I, JACOB GCSHRING, at the city of Frankenthal, Kingdom of Bavaria, German Empire, have invented Improvements in Steam-Generators andFurnaces, of which the following is a specification.

This invention relates to an improved steam generator or drum and furnace, by which a nearly perfect combustion and utilization of the fuel, fire-gases, and smoke, together with a rapid generation of steam with less danger of explosion, is obtained.

The invention consists, essentially, of a steam boiler of any approved construction, having a drum or generator, which is arranged transversely below the boiler and connected thereto by interior circulating-tubes, together with a furnace with an inclined and adjustable grate.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section, Fig. 2 a horizontal section on line y 3 Fig. l, and Fig. 3 avertical transverse section on line 90 m, Fig. 1, of my improved steam generator or drum and furnace.

Similar letters of reference indicate corresponding parts.

A represents a steam-boiler, of any approved construction, below which is arranged a drum, B, which is placed transversely to the longitudinal axis of the boiler, and connected to the latter by vertical or inclined connectingtrunks B. The drum B is supported in a suitable manner in the brick-work of the furnace, it resting with its ends in the side walls and bearin g with its rear part against the rear wall of the same. The drum is placed directly over and across the fire, which acts nearly on the entire surface of the same, so that a rapid circulation of the water therein takes place, which is communicated 'to the boiler by means of interior vertical tubes, 0, that lead from the drum through the trunks to the boiler, and are then turned at right angles and extended back to a suitable length within the boiler. The rapid circulation of water by the direct heat of the fire promotes, also, the quick generation of steam without any danger of explosion, as the drum, being below the boiler, can

never be without water as long as there is any water in the latter. The unequal expansion of the walls of the drum is avoided, as thefiregases nearly envelop the same entirely.

The grate D is arranged in a downwardlyinclined position below the generator, extending from the front to some distance from the rear wall of the furnace. The grate 18 charged continuously without raking, the fuel feeding itself gradually downward along the grate. The fuel is thereby heated up, and thus prepared for the final combustion. The fire-gases are compelled to pass nearly around the entire circumference of the generator, they mingling in front of the drum with the gases developed by the newly-fed fuel and with cold air, which enters through a channel, a, and a regulatingslide, b, above the furnace-door. The mingling of the fire-gases with the newly-generated gases and with the atmospheric air produces the entire combustion and the perfect utilization of the fire-gases. The gases of combustion are then drawn over the fire-bridge and through the fines below and above the boiler, and finally passed off through the chimney, their heat being thoroughly utilized in heating up the boiler.

Atmospheric air is admitted to the grate through a hinged door, E, and drawn down along an inclineddeflecting-plate, E, so as to strike the fuel at a point on the grate where the heat is highest, so that it adds to the perfect combustion of the fuel. The door F, above the inclined plate E, is only opened when the fireman desires to clean the grate.

The grate D is hinged at its upper part, and so arranged that its lower part may swing through an arc of a circle, for the purpose of assuming a greater or less degree of inclination, according to the material to be burned thereon. The grate is thereby adapted to burn coal, peat, sawdust, shavings, or other fuel.

The adjustment of the grate can be accomplished at any time during the firing, as the grate is merely moved at its lower part by means of a suitable exterior mechanism until the inclination required forthe fuel to be burned is obtained.

The means shown in the drawings for adjusting the grate consist of a set-screw passing through the plate on which the free end of said grate rests. It is evident, however, that any other suitable adjusting device may he employed.

I am aware that boilers have been arranged 5 transversely over horizontal grates. and that inclined grates are not new; but by the combination set forth I not only secure the advantage of an inclined grate, lmtalso so direct the flames as to burn oli" the gases from the [0 fresh fuel and lap completely around the side and top of the drum.

I claim-- 1. As an improvement in steam-generators and furnaces, the combination of a drum and 15 an inclined grate arranged at one side of and parallel to said drum, hereby the flames are deflected and caused to traverse the side of the drum and over the fresh fuel. as set forth. 2. As an improvement in steam-generators scribing witnesses. v
